Yes — Signal supports media in OpenClaw now.

• Inbound: Signal attachments can be downloaded and passed to the agent.
• Outbound: the agent can send media/attachments back through Signal.
• Limit: channels.signal.mediaMaxMb controls the inbound/outbound cap, default 8 MB.
• Targets: DMs use signal:+1555... / E.164 or uuid:<id>; groups use signal:group:<groupId>.

Example agent ask:

“Send this image file to Signal [phone]”

or via tool-style send, it can use media, path, or filePath as the attachment source, as long as the file is inside the agent’s allowed media/workspace access.

how to enable the outbound capability?

[eternal raven]

First check your version: openclaw --version — if this doesn’t work, version matters.

There isn’t a separate channels.signal.outbound toggle. Signal outbound is enabled when Signal is configured; for agent-initiated sends, make sure the agent has the message tool:

{
  channels: {
    signal: {
      enabled: true,
      account: "[phone]",
      cliPath: "signal-cli",
      mediaMaxMb: 25
    }
  },
  tools: {
    profile: "coding",

    alsoAllow: ["group:messaging"] // or ["message"]
  }
}

If you already use tools.allow, add message / group:messaging there instead — don’t use allow and alsoAllow in the same scope.

Restart + test:

openclaw gateway restart
openclaw channels status --probe

openclaw message send --channel signal \
  --target [phone] \
